FEATURE-BASED DESIGN SYNTHESIS AND PERFORMANCE ANALYSIS OF UNDERWATER BODIES
A design environment has been developed based on the use of a high level computer graphics workstation serving as a front end to a super computer. The design environment is based on the underwater body domain. The designer is able to develop the geometry using GEODES for an underwater hull with fins to operate with either a predominantly laminar or turbulent boundary layer. The hull geometry is then automatically panelled by specifying the number of panels, and then sent to the potential flow program MCAERO for the computation of the surface and external flow field pressures and velocities. The displacement and momentum boundary layer thicknesses, shape factor and surface friction coefficient are then computer using the viscous flow program TAPS. The displacement boundary layer thickness computed by TAPS is then used as the input to a design routine in MCAERO yielding a new body shape modified for the displacement boundary layer thickness. This interactive process is repeated until convergence occurs between the two predicted flow fields. The next step in the development of this design environment will be to process the computed data for display in a colour coded three dimensional format using the program RIP.
